There’s been a debate for a while over whether or not single-sided energy coaching has and benefit over double-sided (doing a one-armed chest press vs doing a traditional barbell bench-press, for instance). There are causes to anticipate it to be higher, reminiscent of getting your obliques concerned in a one-armed chest press, and the truth that the whole load lifted by the 2 sides individually is greater than the whole load in a double-sided elevate. That’s as a result of one facet is normally stronger than the opposite, and the double-sided train may be restricted by the weaker facet. However as mentioned in a latest article in Alex Hutchinson’s Sweat Science column, research have proven combined outcomes till now.
He goes on to assessment a latest research that confirmed a pronounced benefit for single-legged vs. double-legged leg presses and endurance efficiency, nevertheless. The protocol was to alternate legs in a single leg press, vs. elevate with each legs concurrently. The alternate legs led to vital extra enchancment in time to exhaustion in a biking endurance take a look at. This is sensible based mostly on the precept of specificity- it helps if the coaching you do matches the precise motion in your chosen sport. Alternate legs whereas pushing clearly is nearer to the precise biking movement that double-leg presses.
I used to be already doing this as a result of I take pleasure in it. I do “on-bike” leg energy coaching, like standing as much as pedal in an enormous gear up hill, which is near alternating single-leg presses. I additionally love to do single arm presses, that are near a jab in boxing, and the canoe paddling movement which alternates sides. In all these circumstances I benefit from the movement as a result of it simulates an precise sport motion. However that’s simply me. If you happen to take pleasure in double-side actions higher, by all means do them. I agree with Alex’s concluding remarks that you must do no matter sort of energy coaching feels higher for you.
